The surface of the silica gel is coated with cellulose-tribenzoate

OB is a polysaccharide derivative positive phase coated chiral column, and the surface of the silica gel is coated with cellulose-tribenzoate.

OB is currently the most widely used chiral filler in the world. The excellent separation ability and tolerance of OB column have been reported in various literatures.

CHIRALCEL ® OB-H / CHIRALCEL ® OB is used in the normal phase mobile phase.

pressure

In order to extend the service life of the chiral column, it is recommended to keep the pressure below 30MPa.

(For CHIRALCEL ® OB columns, please keep the pressure below 10MPa)

Storage solvent

n-Hexane/2-Propanol = 90/10 (v/v)


Column Care

  • The use of a guard column is highly recommended for maximum column life. 
  • Samples should be dissolved in the mobile phase and should be filtered through a membrane filter of approximately 0.5µm porosity. 
  • The mobile phase should be displaced with Storage Solvent (Hexane / 2-propanol 9:1) when stored for more than one week. 
  • When washing is required, use pure Ethanol at an appropriate flow rate for 3 hours. 


Important Notice

STRONGLY BASIC solvent modifiers or sample solutions MUST BE AVOIDED, because they are likely to damage the silica gel used in this column.
